Recent Advances in Magnetic Field-Enhanced Electrocatalysis

Magnetic field-enhanced electrocatalysis has recently emerged as an advanced strategy with great application prospects for highly efficient energy conversion and storage. Directly or indirectly, the magnetic effect has been proved positive in various electrochemical reactions. This review starts from a brief introduction and analysis to the possible mechanisms (magnetothermal effect, magnetohydrodynamic effect, Maxwell stress effect, Kelvin force effect, and spin selectivity effect) of magnetic field-enhanced electrocatalysis. The recent advances in magnetic field-enhanced electrochemical reactions, including hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, and CO2 reduction reaction, are comprehensively summarized. The review ends up with perspectives on the future research of taking advantage of magnetic effect for enhanced electrocatalysis.
